Adefemi Adekeye, 21, was arrested Wednesday night on a charge of aggravated robbery.

Toyin Dada, 21, was arrested Thursday, also on a charge of aggravated robbery.

The university and head coach Larry Coker released statements that they had been made aware of the arrests but would not comment because of the ongoing police investigation.

According to the arrest warrant affidavit for Adekeye, a man went to his off-campus apartment Tuesday to buy an ounce of marijuana for $300, but when he got there Adekeye and another man robbed him at gunpoint.

The man was pistol-whipped before being thrown out of the apartment, according to the report. He then flagged down a constable for help, which led to an hours-long SWAT standoff while negotiators attempted to coax the armed men out of the apartment.

When they entered the apartment, however, they found it was empty.

An arrest warrant affidavit for Dada was not available Thursday night.

According to the university, Adekeye is a junior kinesiology major who started classes in fall 2010. He is also listed as a nonscholarship walk-on to the football team, for which he played safety.

Dada is listed as a senior general business major who started classes in fall 2011. He is also listed as a nonscholarship walk-on who played cornerback.

“We were made aware of Adefemi Adekeye’s arrest on Wednesday night and have dismissed him from our program. Due to the ongoing investigation by law enforcement, we will not make any further comment on this situation,” UTSA head coach Larry Coker said.

"On August 1, we were notified that UTSA student Adefemi O. Adekeye was arrested by the San Antonio Police Department in relation to an incident that occurred off-campus. We have no further comment at this time," UTSA Spokesperson Christi Fish said.
